Another object is to provide a means for depressing the rear of thespring assemblage which forms the spring base for loose seat cushionswhen the device is folded into seating position,

whereby to prevent a rigid holding of this portion of the spring base ata non-depressed level and whereby proper depression of adjacentforwardly disposed portions is facilitated and a forwardly slopingconditions is prevented when the seat is occupied.

A further object is to provide a bed davenport in which the portioncomprising the sleeping equipment or bed is not utilized directly as aseat cushion and is not subjected to the severe usage received by a seatcushion.

Further objects of this device reside in any novel features ofconstruction or operation or novel combination of parts present in theema,ss5,ose

hinged juncture as the sections are folded. The

axis of the hinge means interconnecting the front and back sections isdisposed below the hinged juncture of the spring assemblages when in thehorizontal extended position. By virtue of this axial spacing of thearticulating means bodiment described and shown in the accompanyingdrawings, whether within or without the scope of the appended claims andirrespective of other specific statements as to the scope of theinvention contained herein.

In accomplishment of these objects I have provided a supporting frame, avertically disposed, coil spring equipped back rest section whichextends below the seat cushions which are separate units. Articulatedwith the back rest section is a horizontal section similarly equippedwith a coil springassemblage and which is disposed near the bottom ofthe frame and serves as a sprin base for supporting the separateremovable cushions.

The sections are provided with interlocking means for securing them inright angled co-relation and the rear or back-rest section is providedwith trunnions at each end which provide a longitudinal axis upon whichthe interlocked sections may be rotated. This axis is located in spacedrelation with the axis of the articulating means which interconnectsthesections and so located upon the rear section that when it is rotated toa horizontal position it will be disposed at a higher level than theseating height of the closed device.

The frame of the device has end members which support the trunnions ofthe back rest and the latter are provided with means whereby they may beshifted forwardly as the rear section is rotated from-a back restposition to a horizontal position.

Inter-connecting means associated with the end members provide a meansfor shifting the trannions forwardly and backwardly as the rear sectionis rotated respectively to and from a horizontal position. 4 v

The interlocking means for holding the sections in right-ang'lrirelation are adapted to also form supports fort-1e front section whenthe latter is lowered to a bed position co-planar with the horizontallydisposed back rest section, the supports being adapted to rest on aportion of the frame. The sections of my device have separate frameswhich carry the articulating means for interconnecting the sections andcarry separate coil spring assemblages which support a. continuousunitary pad of uniform thickness which forms the surface of the bed, Thespring assemblages are interconnected at their juncture by dual parallelhinge means atthetops thereof which permits the spring assemblages andthe padding thereon to fold along two parallel lines when the sectionsare folded to right angled relation. Means is provided for depressingthe springs along their occurring at the top of the springs and in thepadding thereby keeping the padding tight and at the same timedepressing the padding at this point so that when the front section isdisposed in a horizontal position near the bottom of the frame the rearportion of this section will be predepressed. Such pre-depression alongthe rear of this section permits the proper depression of forwardlydisposed portions thereof when used as a spring base for supportingseparate loose cushions. With this structure the rear of the frontsection is not held rigidly at an undepressed level which would resultin a forwardly sloping structure when depressed in other regions.

It will be noted that provision is made for a continuous pad of uniformthickness which is extendable into a flat, even bed surface and whichwhen folded is depressed at the juncture of the sections in a mannerthat prevents strain upon the pad when the front section is depressed bythe user and which allows the free depression of the spring baseforwardly of the juncture which assures a comfortable .seat.

While the flat, even surface is provided for the bed sections, asuitable oval or crowned seat structure is obtained through the use ofseparate loose cushions in combination with the front bed section as aspring base for the cushions. This combination has the additionaladvantage of a deep spring seat comprising a spring filled cushion and asoft front spring base for a cushion support. Through this arrangementthe front bed section is not subjected to the hard usage received bysimilar sections of conventional devices inasmuch as the cushions areutilized as direct seating equipment instead of the bed section.
